The Baikal yellowfin (Cottocomephorus grewingkii) is a freshwater fish of the family Cottocomephoridae that grows up to 19 cm.
Description
The Baikal yellowfin is a slender, semi-pelagic sculpin of the family Cottocomephoridae reaching about 19 cm and endemic to Lake Baikal. Unlike most sculpins, which live on the bottom, this species swims freely in the open water; the brownish body has large pectoral fins and yellowish fins, to which the name refers. It lives semi-pelagically in the deep lake and near rocky shores and feeds on zooplankton, mainly amphipods, and on fish larvae. In spring it moves to shallow, rocky shores to spawn, where the male guards the clutch laid on stones. The Baikal yellowfin forms an important link in the lake's food web and is prey for the Baikal seal and for commercial fish.
